To improve the correlation of externally visible lesions
in skin and subcutaneous fatty tissue with MRI findings,
external strand-shaped markers were developed and
tested. The visibility of the markers in photography and
MRI, and quality of the final registration were
investigated. Visualization of the markers and internal
soft tissue damage was possible using a combination of
sequences. Using manual feature detection followed by an
affine transformation, MR images were registered to
photographs documenting external and internal damage.
Selected points in the registered MR images and
photographs were used to evaluate the registration,
giving an overall RMSE of 1.05 mm (95%CI[0.46;1.42]).
